ADHESIVE COMPOUND.

Specification of Letters Patent.

Patented April 2. 1907.

Application filed October 11, 1906. Serial No. 338,397.

Be it known that I, MONl-I R. Isaacs, a citizen of the United States,and a. resident of the city of Philadelphia, State of Pennsylvania, haveinvented certain new and useful Improvements in Adhesive Compounds, ofwhich the following is a full, clear, and complete disclosure.

The object of my invention is to produce an adhesive compound or gluefrom any; casem 01' other su table )roteid and lime,

"U" T l wInZiIi compound will not reati y coagulate or disintegrate andin which a thorough dis 5 tribution of the lime throughout-the casein iseil'ected.

In carrying out my invention I combine casein or other sui tal,;lc proteid with lime, a

suitable iluorid. and a compound of ciilcium I and mat.

ates and aluminatcs of calcium and gredients which are mixed with thecasein will be less than would be used in making a more slowly-settingglue.

The fluorid which 1 preferably use is the iiuorid of sodium: but theil'torid of iotasslum.ammon um. orany ot icrsim ari uorit may besubstituted without departing from s the spirit and scope of myinvention.

The compound of calcium and magnesium which I employ generally containscalcium silicate. calcium aluminat-c, magnesium sihcatc. and magnesiumalununatc. Almost any good hvdraulic cement. such as II osed ale cementPoriland cement. contains these substances in varying proportit'ins; butIprcfer to use Portland cement, since I have found that good results maybe obtained from its use.

A cement or glue made in accordance with my invention and which givesgood results consists of the following ingredients in the proportionsstated below: casein. one hundrcd parts; lime. nine to fifteen parts;iltlOlltl of two to eight parts.

It is sometii'nes desirable for commercial f purposes to put up myimproved glue or ce- L and alummates of calcium and magnesium.

Inent into separate packages, one containing 'ifli um or acompound"coiitamiii'g iroportions of the above ingredientstwo to tenparts; Portland cement i l the casein and the other the remainingingredients suitably mixed together. When it. is desired to use theglue, it is merely nectssary to take from ten to forty parts of the commund of fiuorid, lime, and Portland cei menla nd ihoroughly mix it witha suitable quantity of water and one hundred parts of casein, or in somecases itwould be merely necessary to package the lime, iluorid of soda.and Portland cement suitably propo'rti onized, andiefthe usei 'iiiix thesame with water and any suitable case ip or other prot eid. In stillother cases the fluorid may be mixed with the casein and theremainingingredients I separately packaged together. While I havedescribed the several ingrei dient s and the manner of combining thesame, i l

I do not desire to be limited to the particular proportions and amountsof the same as above stated, since a composition of matter containingthe above or similar ingredients in any proportions or quantities isfully within the scope and objects of my invention.

I Having thus described my invention, what I claim, and desire toprotect by Letters Patent of the United States, is

1. An adhesive compound consisting of a proteid, lime, a fluorid, and acompound containing calciuni and magnesium.

2. An adhesive compound consisting of f casein, lime, a fiuorid and acompound containing calcium and magnesium.

3. An adhesive compound consisting of casein, lime, a fluorid, and acompound of the silicates and aluminates of calcium and magnesium. 4.
